I always believed that sex doesn't have to be the "last barrier" before the FMC completely fell under the NTR antagonist's influence, and I am glad to see this game explore exactly that trope - Luna/Nova uses sex as a means of currying favor and protect the mission.
Instead, it will take a look at how FMC's resentment towards her husband slowly builds up over time, with each successive failure on his part pushing her deeper in the arms of the "stronger" man - at first, to shield him from backlash, but by the end, out of need for security/comfort that her "weak" husband has proven incapable of providing.
The only downside being that the game was rigged against Aiden from the start, being poisoned with a neuro-toxin to diminish his competency; a noteworthy blemish on otherwise an exemplary story of betrayal.
A considerable improvement over TTP, though the distinct difference in theme & setting does mean that TTP still holds its own in this NTR battle - especially the "A better life" ending, which I find unlikely to happen here... at least not in as wholesome of a way (Luna becomes Vargas' wife & Queen of the Nox criminal empire?).
